The world is still a jungle- though propaganda, bribery, media manipulation and political lobbying have changed the "brute force" equation somewhat.
We all know that nations and tribal groups take and hold whatever territory they physically can. The objective "truth" of territorial claims are often just as nebulous as discerning (and propagandizing about) who is a "terrorist" and who is a "freedom fighter".
I don't oppose Israel's right to exist, or defend itself. I just don't want them doing it on my nickel, or by manipulating the American political system (lobbying and intimidation by AIPAC, ADL of B'nai B'rith, AJC, JDL, etc.) the media (which hardly ever questions American aid) or by endangering the freedom of people everywhere ("hate speech" and "hate crimes" laws, laws making it a criminal offense to question the Jewish version of the Holocaust, etc).
That famous question, "Have you no sense of decency?" must soon be asked of Israel and its worldwide support system. Is there any price to pay, any manipulation or endangerment of people and nations across the world, any crime that needs to be committed (attack on USS Liberty, Pollard's espionage [which cost the US $4-5 billion and put secrets in the hands of China and the Soviet Union], selling Phalcon radars and other weapons to China, bugging the US State Dept, assasinations, massacres by Ariel Sharon, etc. etc.) that is too high a price to pay for Israel's continued existence? If the answer to that question by people with the power to make American foreign policy, extract billions from the US taxpayer and perhaps unleash war and nuclear weapons is "No", then we are in for a lot of pain.
